We provide several different pages of information to assist in solving many types of problems associated with the MBR. Please check out the links to the right for specific help, such as the Reference page which provides the available options and syntax for using MBRWizard, or the Examples page which shows some general examples of using MBRWizard. Also, make sure you check out the Common Problems page, which discusses some of the common issues experienced when the MBR becomes corrupt, and how to survive in disaster recovery mode. For additional information on the Master Boot Record please check out What is the MBR? for a detailed description of the purpose, layout, and placement of the MBR.

A command line application such as MBRWizard is often used in scripts and other processes to assist in task automation. In order to properly address potential problems when running MBRWizard, a valid return code (errorlevel) will always be returned at program exit, which enables you to determine the success or failure of any operation. A return value of 0 (zero) indicates success, while values >0 indicate failure. By specifying the /result switch on the command line, the return code and description will be displayed on the screen for troubleshooting purposes.

Please keep in mind that MBRWizard supports only partition entries located in the MBR, this means Primary and Extended partitions only. There is currently no support for logical partitions. Also, please note that all disk and partition operations are zero based, this means disk 0 is the first disk in the system, partition 2 is the third partition, etc.
